在leetcode上刷题的时候,偶然看到一位仁兄总结的关于寻找数组的子集(78,90)、全排列(46,47)、在数组中找出等于固定值的元素的集合(39,40)、找出字符串回文子串的集合(131),感觉很惊喜,所以搬运到这里分享给大家,下边是原文链接,里面也有很多讨论。https://discuss.leetcode.com/topic/46161/a-general-approach-...
在解决LeetCode 0368问题时,如何优化算法效率? Largest Divisible Subset Desicription Given a set of distinct positive integers, find the largest subset such that every pair (Si, Sj) of elements in this subset satisfies: Si % Sj = 0 or Sj % Si = 0. If there are multiple solutions, return...
Given a non-empty array containing only positive integers, find if the array can be partitioned into two subsets such that the sum of elements in both subsets is equal. Note: Each of the array element will not exceed 100. The array size will not exceed 200. Example 1: Input: [1, 5,...
